Title: Improvements relating to automatic feeds for lathes and the like
IPC: B23B7/14
Filed: 1955-11-21
Abstract: 783,151. Copy-turning; lathe-details. WARNER & SWASEY CO. Nov. 21, 1955 [Dec. 20, 1954], No. 33298/55. Class 83 (3). In a lathe &c. having work and tool-supporting members relatively movable in a first direction, means are provided which tend to produce relative movement in a second direction but which are prevented from acting by stops which are successively tripped to permit the second movement to be performed in steps. A base 23, Fig. 3, for attachment to a lathe-turret F, Fig. 1, carries a tool-slide 22 having a leadscrew 32 fixed thereto at 33 and carrying a cutter 20. A nut 28 engages the lead-screw and is rotatably-urged in the " out-feed " direction by a volute-spring 36 and one or more springs 41 acting directly on the slide. Collars 46, each having a peripheral step 49, Fig. 6A, are adjustably secured by set-screws to the nut, with the steps 49 in different axially-aligned positions so that each in turn may engage one of a series of pivoted dogs 51 to hold the nut against rotation. The dogs 51 are held in contact with collars 46 by spring-detents 65, but the one engaging a step 49 may be tripped by one of a set of stops 64, Fig. 1, adjustable on a grooved-bar 79, to allow the nut 28 to rotate until the next step is engaged by its dog, thus giving the tool an out-feed to an extent determined by the rotational spacing of the steps 49. As the turret F is traversed along the bed towards the headstock, the stops 64 act in succession to cause the tool to produce stepped work as shown in Fig. 1. The initial position of the tool-slide 22 is adjusted by rotating the leadscrew 32 in the slide at 33, by a wrench applied at 85, after releasing a clamping-screw. The tool is re-set, after an operative traverse, by rotating the nut 28 through a handle 84, the spring 36 being thereby wound-up as the tool is fed in. Centre-rests. The end of the work passes through an aperture 88, Figs. 2 and 3, in the base 23, and is supported, ahead of the cutter 20, by two rollers 91, each carried by an arm 93 having an arcuate portion 95 seating in a bore 96 in a bracket 97 secured to the base by screws 104. The portions 95 are clamped in bore 96 by conical collars and a central bolt 100, the thrust of the work being resisted by screws 101 adjusted against the arms 93.

Title: Improvements in means for facilitating the changing of gears on motor vehicles
IPC: F16H59/00
Filed: 1928-11-15
Abstract: 325,263. Morris, J. N., and Bone, C. C. Nov. 15, 1928. Facilitating changing speed. - Means for making shockless gear changes at the right moment comprises an auxiliary gear-box with a differential for each speed associated with a disc such as 2, Fig. 1, which is brought to rest, or nearly so, when the teeth about to be enmeshed are synchronized, as described in Specification 309,740. When the disc 2 has come to rest and is reversed in either direction, the gear change in the main gear-box is automatically completed. In the arrangement of Fig. 1, when the disc 2 is reversed in either direction, a ball 6 rolls between two stops 7 over a swell on a pivoted spring lever 3 and so makes and breaks an electric circuit at switch 8. In another arrangement shown in Fig. 2, reversal of disc 2 oscillates a pivoted strut 10 over a contact 15, where the circuit is made and broken. This momentary current in a solenoid 34, Fig. 3, withdraws a trigger 32 and sets selector-bar 23 free to effect a changing movement of gears 25, 26 determined by the stressing of springs 29, 30. A control lever 16 moves in a gate 17 and is secured to a shaft 18 which moves endways to select one of a number of bars such as 23. A switch 39, Fig. 5, upon the shaft 18 brings into circuit the appropriate synchronizing switch 8 of Fig. 1. Rocking of lever 16 and shaft 18 through finger 20 slides a forked block 21 on the selected bar 23 so as to compress spring 29 or spring 30, the bar 23 being held by trigger 32 until the disc 2 has stopped and reversed on synchronization. The lever 16 is held at the end of a gate slot by a tension spring 36, Fig. 3, which extends from a fixed pin 37 to a crank 35 which has been turned past its dead centre to one side or the other. A single trigger such as 32 may engage two selector bars simultaneously.

IPC: F02M69/00
Filed: 1935-12-05
Abstract: 448,171. Spray carburetters. SOC. GENERALE DES CARBURATEURS ZENITH, 10, Rue Petitot, Geneva, Switzerland. Dec. 5, 1935, No. 33763. Convention date, Dec. 6, 1934. [Class 7 (iii)] The pressure at which fuel is sprayed is rendered independent of any inclination of the carburetter by applying the end 10 of a weighted lever 8 to the centre of a diaphragm 4 which forms one wall of a fuel chamber 3 and controls the admission valve 7 thereto, the lever being so weighted and arranged that the plane through the axis L and centre of gravity G is at right angle to a line joining the centre of the diaphragms 4 to the spraying orifice 2 ; the thrust of the lever on the diaphragm then balances the pressure exerted thereon by the liquid column between the diaphragm and the spray orifice. In practice, to avoid leakage when the carburetter is not in use, the spray orifice is disposed slightly above the theoretically correct point. As shown, the spraying orifice is in the mixing chamber, but it may be disposed in an intermediate chamber to which emulsifying air is admitted. The diaphragm may also be spring loaded.

Title: Sequential pulse generator
IPC: H03K5/00
Filed: 1961-09-21
Abstract: 994,366. Transistor pulse circuits. WESTON ELECTRIC CO. Inc. Sept. 21, 1961 [Oct. 11, 1960], No. 33790/61. Heading H3T. A circuit for generating a sequential pair of pulses, one on each of two lines comprises two monostable multivibrators each employing a separate transistor for the input stage and two transistors for the output stage, the second output transistor in each case also serving as the first output transistor in the other multivibrator. When one multivibrator is triggered, a pulse is fed to one line followed by a pulse on the other line, whilst if the other multivibrator is triggered, the order of pulses on the two lines is reversed. Monostable multivibrators.-Fig. 3 shows a circuit in which transistors Q1, Q3, Q4 form one multivibrator and Q2, Q4 and Q3 form the other. In the stable state, transistors Q1, Q2 are off and Q3, Q4 on. When a trigger pulse is received from source S1, transistor Q1 becomes conductive cutting off Q3 and initiating a pulse T1 at output 1. When C1 has discharged via R1, Q3 becomes conductive terminating pulse T1. The change in collector voltage of Q3 is passed by C3 to the base of Q4, cutting off Q4 and initiating a pulse T2 on output 2. When C3 has discharged, Q4 becomes conductive and Q1 non-conductive, terminating the sequence. Transistor Q2 is held non- conductive during the sequence by the charge on C4. Diode D2 prevents astable operation. If a trigger pulse is received from S2, a pulse sequence T3, T4 is generated in the reverse order by transistors Q2, Q4, Q3. Negative pulses, the duration of which is equal to T1+T2 or T3+T4 may be obtained from the collectors of Q1 or Q2. Generating bipolar pulses.-The input resistors K19, R20 of transistor Q5 in Fig. 5 are connected to outputs 1, 2 of Fig. 3. Q5 is biased to class A so that a bipolar square pulse is generated each time a pulse sequence is received. The harmonics are filtered out at L1, C11 and the resulting bipolar sinusoidal pulse is passed by the emitter follower Q6 to output terminals. The output pulses start with either a negative or a positive half cycle depending on whether a trigger pulse is received from S1 or S2 in Fig. 3.

Title: Improvements in or relating to coil unloaders for strip reels
IPC: B21C47/24
Filed: 1936-12-10
Abstract: 483,397. Load - handling machines for coils &c. STEVENS, A. H. (United Engineering & Foundry Co.) Dec. 10, 1936, No. 33956. [Classes 78 (i) and 78 (iii)] [Also in Group XXXII] A coil unloader for use in a continuous hot strip mill between a strip reel and coil-receiving means, such as a conveyer, comprises a tiltable transfer device which automatically adapts itself to coils of different width. The coil 3 is stripped off the mandrel 2 of a reel 1, by means not shown, on to a concave carriage 17 which is supported at one end by rollers 16 riding in a channel 14 in each of the parallel vertical sides of a frame 11, and at the other end by a shaft 21 riding in the eye of a link 22 rigidly mounted to a shaft 23 journalled in the frame 11. The shaft 23 extends through the frame 11 at one side to carry a crank on the pin of which are attached balance weights, the number of which is chosen according to the estimated weight of the reel 3. The stripped reel abuts against back uprights 18 on the carriage 17 and its weight tilts the link 22 against the balance weights till the carriage strikes against an extending arm 27 on the frame 11. The frame 11, together with the carriage 17 and coil 3, are then lowered till the uprights 18 pass between the sprockets 6 of the conveyer and the coil 3 lies on the chairs 4 thereof, the lowering being effected by spur gearing 31, 32. The shaft 33 of the wheel 32 is driven by an electric motor through worm-gearing, which does not allow a heavy coil to fall at a greater rate than a light one, the rate in each case being that allowed by the normal speed of the motor. In order to permit the unloader to transfer coils from a reel which is not in line with a conveyer, or from several reels on to a single conveyer, the device may be mounted on a truck having wheels 41 riding on rails 42 at one side and rollers 43 on the other side running in an H-section beam 44 which prevents tipping of the apparatus about the rail 42 when very heavy coils are being manipulated. The truck is driven along the rails by an electric motor working on both wheels 41 through wormgearing. When a small coil is being transferred, filler blocks are placed on the carriage 17 to prevent its rolling sideways. In a modification, the carriage has a purely sliding movement in the frame 11, being advanced to receive the coil, and retracted carrying same, by a piston operated by fluid pressure either automatically or at will. The frame 11 is tilted through 90‹ by a toothed segment engaged by a pinion driven by a motor through worm-gearing. In this form the apparatus is stationary, and the conveyer tail is combined therewith.
